REED FOR WEAVING LOOMS.

Application led September 24, .1920., Serial No. 412,573.

To all whom t may concer/n:

Be itknown that I, CHRISTOPHER T. 'Melon a citizen of the UnitedStates, residinofat Appleton, county of Outagamie, and Sbtate of Wisconsin, have invented new and useful Improvements in Reeds for Weaving Looms, of which the following is a specilication.

This invention relates to improvements in reeds for weaving looms. i

Objects of this invention are to improve the construction of reeds for loomsgto provide a reed in which the dents are individu-- ally removable without necessitating the disassembling of the entire reed; to provide a reed in which the correct spacing of the dents is insured, even when a new dent replaces an old dent;rto provide a reed'in which the dents are not crowded toward their central portion; and to providea reed in'which the clamping pressure on the dents maybe varied. Y j

ther objects of this invention are to provide a reed in which faultysthreading thereofmay be corrected by the insertion or removal of a dent without necessitating a rethreading of the reed; and to provide a reed in which the inspection, removal, or correction of any defective and readily made. j

In the drawings Figure 1 is a fragmentary elevation of a reed.

Figure 2 is a'sectional view on line 2 2 of Figure 1.

Figure 3 is a fragmentary section on the line 3-3 of Figure 1.- s,

Figure 4 is a view of one of the dents detached. y y j Figure 5 is a similar view of one of the dent may be quickly The reed comprises upper and lower reed bars indicated generally by the Lreference characters 1 and 2, and end members 3. Between these upper and lower reed bars a series of dents 4: are positioned in. spacedrelation by means cfa series of spacers 5. The

means for clamping the dents and spacers inl position comprises the bar 6 which is inwardly pressed by means of a pair of screws 7 and 8 having locking nuts 9 and 10, respectively, such screws'passing thru and vbeing threaded tothe end bars 3, 'their ends seating in sockets 11 and 12 formed in the clamping bar 6.

y corresponding to metal, and l notches 25 adapted to engage the ribs '16 and The reedbars areeach composed of1rr1` er uV ybers 13 and 14 -formed integrally and extending at substantially right angles to each other.. TheV member 13 is provided'with a dove-tailed groove 15, andthe member v14- with an inwardly projecting V-shaped rib their length, The'v 16 extending thruout j reed bars Ifurther comprise retainers in the inwardly projecting V- shaped ribs 1,8 aligning with the ribs 16. These retaining plates are secured to the member 13by means of j form of plates 17, which are provided with 5 screws 19 countersunlr in the `plate l7gand i is to be done are of extremely thin metal;v

These thantheV distance between then upper and lower surfaces 21 and 22 of the members l and 2, and are provided with notches 23;`

I 'the V-shaped ribs 416 and 18 of the reed bars 1 and 2. Thus when the dentsl are positioned within the reed bars and the retainers 17 are secured inposition, the dents are carried by the V-shaped ribs 16 and`v 17 formed upon the ` reed bars 1 and 2. Itsends are spaced from the surfaces 21 and22. -v 4 H Figure 5 shows a spacer 5, which is formed of ksimilar flat, vrelatively wide, 'is Y `provided with V-shaped 17, and arefurther provided vwith la dovetail projection 26 whichis adapted toengage within either of the dove-tailed grooves 15 formed :in themembers 13 of the reed j bars.r

Thus itv will be seen that whenthefspacer strips .are` positioned with the projections 26 Aslidably held within the dove-tailed grooves 15 and the dents positioned with.; the projections 416` and 18 engaging in the notches 23, such dents may be readily removed or replaced by removing theretainers 17, and withdrawingv the dentfwithout danger of the vcorresponding spacer strips dropping out ofposition. v

.The'end members 3 may conveniently be formed of rectangular metal pieces-having projectingpins 27 ormedeither integrally therewith or formed separately and inserted into openings within such rectangular members 3. These ypins 27 are adapted to.k

plates 4 are of slightly less length engage openings 28 formedin the members,y

iar members 3 are further provided with openings thru which' screws 29 pass, such screws being countersunk in the members 3, and threaded into the members 14 of the reed bars 1 and 2. Thus a secure and accurate positioning of these end members 3 is secured by this method of attachment. Either one or both of the end members 3 may be provided with the adjusting clamping screws 7 and 8.

The clamping bar 6 is of the same width and length as the dents 4, and is correspondingly provided with notches 30 which engage the V-shaped projections 16 and 18 of the upper and lower reed bars and freely slide thereon.

It will be seen that when the clamping Screws T and 8 are tightened, the pressure lis transmitted thru the claming bar 6 to the spacers 5, and to the dents 4. By this construction any pressure that is desired may be placed upon the dents 4t, and also this pressure may be quickly removed by loosening the screws 7 and 8. When these screws are loosened it will be notedthat the ends thereof may be disengaged from the sockets 11 and l2 formed in the clamping bar 6. Upon removal of the retainers 17 the bar 6 may be completely removed if desired; also the dents may be withdrawn by a direct lateral motion. If desired the spacers may be slipped out from engagement with their dove-tailed slots into the spaces 31 at the ends of the reed bars and thereafter removed.

By this construction when any of the reed dents become broken they may be readily removed and other dents may be substituted therefor without dismantling the entire reed; yalso any fault in threading may bev corrected by a proper substitution, removal or addition of dents to effect the desired spacing of the weft.

YVhile this reed is particularly suited to weaving wire, it is to be understood that the scope of this invention is not to be limited, except as defined in the following claims.

I claim 1. In a reed, the combination with alternate dents and spacers, of a reed bar grooved to receive said dents and provided with a recess adapted to receive said spacers, and a retaining element associated with the bar and adapted to secure the dents thereto,

2. In a reed for a loom, the combination with an L-shaped reed bar, of a retainer adapted to be secured to said reed bar, dents adapted to be held in operative position by said retainer, and spacers having means adapted to engage said bar independently of said retainer, whereby said dents'ma'y be separately withdrawn upon removal Of' thev retainer.;

3.
